My experience is the opposite. Since doing acid I find that I can never really get to where I want to be with weed, it kind of ruined it a little bit for me permanently.

As another poster suggested I think maybe it just changed my general perception of getting high rather than any physical changes within myself.

I wish it was the other way around like you seem to be experiencing but I guess it is generally better for my health as I now smoke considerably less weed as it is just like a chasing the dragon sort of situation with me where I smoke and smoke and smoke trying to get to where I want to be then end up just falling asleep and not doing anything because of the fatigue from smoking and never feeling like I attained that high I was looking for.
